System and method for prolonging the life of a battery that is electrically coupled to a load

The present disclosure generally relates to batteries and more particularly relates to a system and method for prolonging life of the batteries.

Batteries are electrochemical devices that store chemical energy and convert the chemical energy into electrical energy to deliver a required power. These batteries are used in wide variety of applications. For example, the batteries are used in portable devices, inverters, motor vehicles, etc. Usually, these batteries drain the stored energy in order to deliver the required power. Even though various rechargeable batteries are currently available, which can be recharged once the stored energy is drained, one of the key concerns associated with the batteries is their battery life. For instance, the battery life of a battery may be a time taken by the battery to completely discharge when connected to a load.

Currently, there are various techniques available to prolong the battery life. For instance, these available techniques aim to prolong the battery life by moving to a battery saving mode, when the load demands for a less power (or the load is in inactive state). However, these available techniques fail to prolong the battery life when the load continuously demands for a power (or the load is in active state).

In order to solve the foregoing problem, the present disclosure provides a system for prolonging the life of the battery while the battery is supplying power to the load. The system may include a charge storage device and the battery. The charge storage device may be connected to the battery such that the battery and the charge storage device formulate a modified tank circuit. Some embodiments are based on the realization that when the battery of the modified tank circuit is supplied with a specific voltage at a specific time, an internal resonance within the battery and the charge storage device may occur. As a result, a chemical reaction within the battery may occur, due to which free electrons may be released. These released free electrons may lead to an additional power. Thereby, the additional power may be extracted from the battery. This additional power extracted from the battery may be used to charge the charge storage device. Once the charge storage device is charged, the charge storage device may be configured to recharge the battery. Accordingly, the life of the battery may be increased (or prolonged) beyond the conventional life of the battery.

In an example embodiment, the charge storage device may supply, to the battery, the specific voltage. In order to supply the specific voltage at the specific time, the system may further include a controller connected to the charge storage device. The controller may be configured to compute a resonance frequency. Based on the resonance frequency, the controller may be configured to control the charge storage device to supply the specific voltage. In an example embodiment, the controller may include a timing circuit. The timing circuit may generate, based on the resonance frequency, control signal(s) to control the charge storage device. Further, the controller may control the charge storage device to: (i) charge while the battery is discharging and (ii) discharge while the battery is charging.

According to some embodiments, the controller may control the charge storage device to supply the specific voltage to the battery at the specific time defined by the resonance frequency, while the battery is under the load. In these embodiments, the system may prolong the life of the battery while the battery is under the load. Additionally, when the load demands for more power than an operating power of the battery, the system may be configured to use the additional power extracted from the battery to provide the power to the load. Accordingly, the disclosed system may be used to prolong the life of the battery and/or provide more power to the load as per the requirements.

illustrates a block diagram of a tank circuit, showing an overview of principles of the tank circuit, according to some embodiments of the present disclosure. As illustrated in, a tank circuitmay include at least one capacitor (e.g. a capacitor) and at least one inductor (e.g. an inductor), among other things. The capacitorand the inductormay be electrically connected by a conducting material. The tank circuitmay store energy. For example, the capacitormay store the energy as electric field (E) between plates of the capacitor, depending on a voltage across the plates. The inductormay store the energy as magnetic-field (B), depending upon a current passing through a coil of the inductor

In an exemplary case, when the inductoris connected across the capacitor(e.g. a charged capacitor), the voltage across the capacitormay drive the current through the inductor. Thereby, the magnetic-field (B) may be built around the coil of the inductor. As a result, the voltage across the capacitormay fall to zero as the charge is used for driving the current through the inductor. At this point, the energy (i.e. the magnetic-field) stored in the coil of the inductorinduces a voltage across the coil, because the inductoropposes the change in a flow of the current. The induced voltage may cause a current to recharge the capacitor. Due to Faraday's law, an electro motive force (EMF) which drives the current is caused by a decrease in the energy (i.e. the magnetic-field) stored in the inductor, thus energy required to charge the capacitoris extracted from the energy (i.e. the magnetic-field) stored in the inductor. When the energy in the inductoris completely dissipated the flow of current may stop and the charge may again be stored in the capacitor. Then the cycle will begin again, with the current flowing in an opposite direction through the inductorfrom the capacitor. In this way, the charge flows back and forth between the capacitorand the inductor. Thereby, the energy may oscillate back and forth between the capacitorand the inductor

In an example embodiment, the oscillation of the energy may occur in the tank circuit, when the tank circuitis provided with an external current of a specific frequency at which an inductive reactance of the inductorand a capacitive reactance of the capacitorare equal in magnitude. Hereinafter, the specific frequency and resonance frequency may be interchangeably used to mean the same.

Some embodiments are based on the recognition that when the tank circuitis applied with the external current with equivalent frequency as the resonance frequency of the tank circuit, the oscillation of the energy may occur with large amplitude voltages and currents even if a quantity of the external current applied to the tank circuitis small. Some embodiments are based on the realization that the principles of applying the external current of the resonance frequency to the tank circuitcan be extended to increase (or prolong) a life of a battery. To this end, some embodiments formulate a modified tank circuitby replacing: (i) the capacitorwith the batteryand (ii) the inductorwith a charge storage device. Further, some embodiments aim to transform the principles of applying the external current of the resonance frequency to the tank circuit, to principles of applying a specific voltage at a specific time defined by the resonance frequency, to the battery. In an example embodiment, the charge storage devicemay supply (or provide), to the battery, the specific voltage at the specific time defined by the resonance frequency. For instance, the charge storage devicemay include a bank of capacitors, a power supply, or a combination thereof. For instance, the batterymay be a rechargeable battery that can discharge the energy to an external load and charge again after being discharged by applying the current across its terminals. For example, the batterymay be a lead-acid battery which discharges (or charges) the energy due to a chemical reaction within the battery, when a load (or a power supply) is connected across terminals of the battery

Some embodiments are based on the realization that the supply of the specific voltage at the specific time to the batteryenables an internal resonance within the batterydue to which the chemical reaction within the batterymay occur. As a result, an additional power may be extracted from the battery. For example, the supply of the specific voltage at the specific time to the batteryenables to break free electrons within the battery. These free electrons may lead to the additional power. Further, these free electrons may be used to charge the charge storage device. Furthermore, the charge storage devicemay recharge the batteryusing the same free electrons with which the charge storage devicewas charged. Thereby, a life of the batterymay be increased. For instance, a system for implementing the principles of applying, to the battery, the specific voltage at the specific time is as explained in the detailed description of.

illustrates a block diagram of a systemfor prolonging the life of a battery, according to some embodiments of the present disclosure.is explained in conjunction with. The systemmay include a controller, a charge storage device, and a battery. The charge storage devicemay correspond to the charge storage device. The charge storage devicemay be a circuitry that includes, but is limited to, a plurality of capacitors and a plurality of relays. The plurality of capacitors may store the energy and/or discharge the energy as the electric field. The plurality of relays may enable a series configuration of the plurality of capacitors to be connected across terminals of the batteryand/or a parallel configuration of the plurality of capacitors to be connected across the terminals of the battery. Additionally or alternatively, the charge storage devicemay include a power supply.

The batterymay be the rechargeable battery, for example, a lead-acid battery which may execute a discharge process (or a recharge process) due to the chemical reaction within the battery, when a load(or a power supply) is connected across the terminals of the battery. For instance, the loadmay be a DC motor, an electric vehicle, and/or the like. For instance, the discharge process of the batterymay be as explained in the detailed description of.

illustrates a block diagramshowing the discharge process of the battery, according to some embodiments of the present disclosure. The batterymay include two electrodes, for example, an anode made up of lead (Pb) and a cathode made up of lead peroxide (PbO). Further, the batterymay include an electrolyte which may be a dilute sulfuric acid (HSO). The electrodes may be placed within the electrolyte as shown in. Further, the electrodes may be connected to the loadvia a switchusing a conducting material. When the switchis closed, the discharge process (i.e. electrons may flow from the anode to the cathode) of the batterymay begin due to chemical reaction within the battery. For example, the chemical reaction within the batteryduring the discharge process is: Pb (Lead)+PbO(Lead peroxide)+2HSO(dilute sulfuric acid)→2PbSO(Lead sulphate)+2HO (Water). As a result of the chemical reaction, the electrons may flow from the anode to cathode, while the Lead sulphate gets accumulated on the electrodes and the dilute sulfuric acid is further diluted. Alternatively, when the switchis open, the discharge process of the batterymay stop.

Referring back to, the batterymay be electrically connected to the charge storage deviceto formulate a modified tank circuit (e.g. the modified tank circuit), while the batteryis connected to the load. The charge storage devicemay be further connected to the controller. The controllermay be a micro-controller based circuit. According to an embodiment, the controllermay be configured to receive a user input. For instance, the user input may include one or combination of a specification of the battery, a specification of the charge storage device, and/or a specification of the load. For example, the specification of the batterymay include information about the batterysuch as impedance of the battery, an operating voltage of the battery, an inductance value associated with the batteryand/or the like. For example, the specification of the charge storage devicemay include information about the charge storage devicesuch as impedance of the charge storage device, a capacitance value associated with the charge storage devicewhen the plurality of capacitors is in the series configuration, a capacitance value associated with the charge storage devicewhen the plurality of capacitors is in the parallel configuration and/or the like. For example, the specification of the loadmay include information about the loadsuch as impedance of the loadand/or the like. In an alternate embodiment, the specification of the battery, the specification of charge storage device, and/or the specification of the loadmay be predefined and stored within a memory associated with the controller.

According to an embodiment, the controllermay be configured to compute a resonance frequency value based on one or combination of the specification of the battery, the specification of charge storage device, and/or the specification of the load. For instance, the resonance frequency (f) may be mathematically computed using:

where the notation L is the inductance value associated with the battery, and the notation C is the capacitance value associated with the charge storage device. According to an embodiment, the resonance frequency may define a time at which the batteryshould be provided with the specific voltage to achieve the internal resonance within the battery. Accordingly, the controllermay be configured to control the charge storage deviceto supply the specific voltage to the battery, based on the computed resonance frequency. To this end, the charge storage devicemay be configured to supply, to the battery, the specific voltage at the specific time defined by the resonance frequency. For example, when the batteryis supplied with the specific voltage, the batterymay reach an overvoltage condition due to which the chemical reaction may occur within the battery, leading to freeing up of electrons within the battery. As a result, an additional power may be extracted from the battery. Further, this extracted additional power may be used to charge the charge storage device. Further, the charge storage devicemay recharge the battery, once the charge storage deviceis charged. Thereby, the life of the batterymay be increased.

In an example embodiment, the plurality of capacitors of the charge storage devicemay be pre-charged with the power supply. The plurality of capacitors of the charge storage devicemay be used to supply the specific voltage to the battery. Specifically, the controllermay control the plurality of relays of the charge storage devicebased on the computed resonance frequency such that the plurality of relays change the configuration associated with the plurality of capacitors to make the batteryreach the over voltage condition. In an example embodiment, the controllermay control the plurality of relays to change from the parallel configuration to the series configuration to make the batteryreach the over voltage condition, which may result in prolonging the life of the battery.

In an example embodiment, the controllermay control, based on the computed resonance frequency, the charge storage deviceto supply the specific voltage to the batterywhile the batteryis under the load. Accordingly, the additional power extracted from the batterydue to the supply of the specific voltage may not only be used to charge the charge device storage, but also may be used to power-up the loadwhen the loaddemands for a more power than the operating voltage of the battery. Therefore, the systemmay be used to prolong the life of the batteryand/or provide the loadwith more power as per the requirements.

Here for the purpose of explanation, in, the charge storage devicewith the plurality of capacitors to supply the specific voltage and to store the additional power extract extracted from the batteryis considered. However, the plurality of capacitors may be replaced with other charging and discharging devices that are known in the art, without deviating from the scope of the present disclosure. Here for exemplary purpose, in, the batterylocated within the systemis considered. Alternatively, the batterymay be located outside the system, and may remain connected to the charge storage devicewhile connected to the load. Further, the components of the systemmay not be limited to the components shown in. For instance, the systemmay also include some additional components that provide additional functionalities to the present disclosure. For instance, various configurations of the systemare as described in the detailed description of-.

For instance, the plurality of capacitorsandmay be two to five (2-5) Farad 12 volt capacitors. The fusemay be configured to prevent the systemfrom an overcurrent condition. For instance, the fusemay interrupt the flow of current within the systemwhen the current within the systemexceeds a threshold current value. The plurality of relaysandare switching devices that enable the series configuration of the plurality of capacitorsandto be connected to the terminals of the batteryand/or the parallel configuration of the plurality of capacitorsandto be connected to the terminals of the battery. For instance, the plurality of relaysandmay be electromagnetic relays.

The controllermay correspond to the controller. The controllermay be the micro-controller based circuit. In an example embodiment, the controllermay include a timing circuit. The controllermay be connected to the charge storage device. The controllermay be configured to compute the resonance frequency (f). For instance, the resonance frequency (f) may be mathematically computed using:

For example, while considering the inductance of batteryto be 0.025 Henry and the capacitance of the plurality of capacitorsandin the series configuration to be 2.5 Farad, the resonance frequency (f) may be equal to 38.4 cycles per minute, which may be equal to 1.56 seconds per cycle.

Based on the resonance frequency, the controllermay be configured to control the charge storage deviceto supply the specific voltage. In order to supply the specific voltage, the plurality of capacitorsandmay be designed and arranged in association with the plurality of relaysandas shown in. Accordingly, to supply the specific voltage to the battery, the controllermay be configured to control the plurality of relaysandto change the configuration of the plurality of capacitorsandwith the battery. In an example embodiment, the timing circuitmay generate, based on the resonance frequency, control signal(s) to control the plurality of relaysandto change the configuration of the plurality of capacitorsandwith the battery.

As a result, the chemical reaction in the batterymay occur. Thereby the additional power may be extracted from the battery. This additional power may be used to charge the plurality of capacitorsand. For example, to charge the plurality of capacitorsandfrom the battery, the controllermay control the plurality of relaysandto enable the parallel configuration of the plurality of capacitorsandto be connected to the battery. Once the plurality of capacitorsandare charged, the plurality of capacitorsandmay recharge the battery. To recharge the batteryfrom the plurality of capacitorsand, the controllermay control the plurality of relaysandto enable the series configuration of the plurality of capacitorsandto be connected to the battery. Thereby, the life associated with the batterymay be increased. With the first configuration of the system, a discharge time of the batterymay be increased by 60% for a given load specification. For instance, the discharge time may be a time taken by the batteryto completely discharge when connected to a load.

For example, the controllermay control the plurality of relaysandto change the configuration of the plurality of capacitorsandto the series configuration. When the configuration of the plurality of capacitorsandis changed to the series configuration, the battery may reach the overvoltage condition due to which the chemical reaction occurs within the battery leading to freeing-up of the electrons. These free electrons may lead to the additional power.

For example, the controllermay control the plurality of relaysandto change the configuration of the plurality of capacitorsandto the parallel configuration. When the configuration of the plurality of capacitorsandis changed to the parallel configuration, the plurality of capacitorsandmay be charged with the additional power.

At step, the methodmay include checking if a second time within the time defined by the resonance frequency is completed. The second time may be a time period obtained by subtracting the first time and the time defined by the resonance frequency. If the second time is not completed, the methodmay wait until the second time is completed. If the second time is completed, the methodmay proceed to step. At step, the configuration of the plurality of capacitors may be again changed to the series configuration to recharge the battery.
